NOTES
The calibration scale is based on standard tests made with oven-dried samples of the various wood
species (between 7% and fibre saturation). Beyond the fibre saturation point (25 % to 30 %) the rea-
dings are approximate only and generally apply to wood that has been dried and re-wetted.
The instrument is calibrated for wood at 20°C. If the temperature of the wood to be measured varies by
more than 5°C, the meter reading can be manually corrected, as follows:
The manual correction of the reading if the wood to be measured is above 20°C:
- 0.5 % moisture content for each 5°C difference.
The manual correction of the reading if the wood to be measured is below 20°C:
+ 0.5 % moisture content for each 5°C difference.
If the wood has been impregnated with a water-borne preservative readings obtained may be higher by
1 to 2 %.
